NSF-61 Annex G Standard

AB 1953 and NSF 61 Annex G

The official AB 1953 bill changes the meaning of term lead free in the Health and Safety Code form eight percent lead for pipes or pipe fittings, and four percent lead for plumbing fittings and fixtures to a weighted average of not more than 0.25 percent lead content within each component that comes into contact with the wetted surfaces of pipes and pipe fittings, plumbing fittings and fixtures effective July 1, 2010. Along with this change brings new standards like the Annex G standard, the modified version of NSF / ANSI Standard 61.

NSF/ANSI Standard 61 was revised in December 2008 to establish requirements for use when a 0.25% lead content requirement needs to be met in addition to current chemical extraction requirements of the standard. The requirements were placed in Annex G - Weighted Average Lead Content Evaluation Procedure to a 0.25% Lead Requirement. In addition, mandatory language placing restrictions on the use of lead as an intentional additive in water contact materials was also added to Section 3.

A request was made to add these requirements to the standard to allow manufacturers the option of being certified to a lead content standard, such as California's Health & Safety Code (Section 116875) commonly known as AB1953. That law, which goes into effect January 1, 2010, applies to any pipe, pipe of plumbing fitting, or fixture intended to convey or dispense water for human consumption through drinking or cooking. A similar law has been enacted in Vermont and is also to take effect January 1, 2010.

The annex was developed through the Lead Task Group of the Drinking Water Additives Joint Committee and includes requirements that enable conservative and consistent application of the lead content evaluation procedure. Highlights include:
